BREECH-LOADING FIRE-ARM.

SPECIFICATION forming part of Letters Patent No. 282,838, dated August7, 1883.

Application filed May 24,1883. (No model.)

To @ZZ whom it may cm1/cern:

Be it known that I, ALEXANDER T. BROWN, a citizen of the United States,residing at Syracuse, in the county of Onondaga and State of New York,have invented certain new and useful Improvements in Breech LoadingFire- Arms, of which the following is a specification, reference beinghad therein to the accompanying drawings.

My invention relates to improvements in that class of breech-loadingguns known as break-down gunsy7 and its object is to improve theconstruction of the breech mechanism, and especially the lock andcooking mechanism of the gun.

The novel features of my device will Abe hereinafter specificallypointed out in the claims.

In the drawings, Figure lis a central longitudinal section of the breechand lock mechanism ot' my gun, showing (partly in dotted lines) one` ot'the hammers in cocked position. Fig. 2 is a similar section, showingbreech closed and hammer in position for striking the cartridge. Fig. 3is a view oi' top lever and connections detached. Fig. 4 is a sectionsimilar to Fig. l, showing the hammer cocked and the connections bywhich it may be cocked by the lever. Fig. 5 is a perspective of thestirrup, cooking-bar, hammer-shaft, and hammer detached. Fig. 6 is aplan showing the bolt for locking the barrels. Fig. 7 isaplan, partly insection, showing eonnectiqn of the top lever and its post with thecooking-link.

My device is intended to enable the sportsman to cock his piece by thebreaking down of the barrels, as is now quite customary in what areknown as hammerless guns, or, without opening the barrels at all, tocock the hammers bythe operation ot' the top lever in a reversedirection from that required to unlock the barrels from their closedposition 5 also, to enable the barrels to be disconnected from thecooking mechanism.

H represents the top lever of a break-down gun. It is apparent that thelever may be applied to the bottom of the stock and engage with the postG in the same manner, it' desirable.

l represents the barrels of my gun; 2, the frame; 3, a lug on thebarrels. In the lug 3 there is pivoted a stirrup, A, which has a hook,

said lever is lifted the hammers, also carried L by shaft C, are carriedback toward their cocked position, and, when full-cocked, are Caught bysears F. The stirrup A extends dowll through the frame and terminates ina comb, a, by

which the stirrup may be swung forward against the pressure of spring s,and its hook A be disengaged from the end ofthe Cooking` lever B, sothat the barrels may be readily 1'0- moved from the frame. XVhen stirrupA is in engagement with lever B, and the barrels are broken down, therising ofthe rear end of lug 3 carries up the stirrup, and the sti rrupin turn lifts the lever and cocks the hanuncrs. Then the lever B risesto the extent ol" its movement, the shoulder b finds a bearing againstframe 2 and thus serves as a stop to prevent further movement ot' thebarrels. pivoted in the lever and hook on the lug as an equivalentconstruction. The top lever, H, by a movement in one direction, unlocksthe barrels. In the drawings this movement is to the right, and servesto disengage catch et from the extension 5 ot' the barrels. Other formsof locking catch may be used. A reverse movement ofthe lever H does notunlock the barrels, but turns the post Gin the opposite direction. Saidpost G has an extension, g, which engages in a notch, c, of link E,which, by a hook, c', at its front end, engages a hook or shoulder, b2,on the cooking-lever l5. Thus when the post Gr is turned to the left thelink E will be drawn back, and by its engagement with lever B said leverwill be rocked, andthe hammers D will be cocked in the same manner as bythe tilting ot the barrels.

The connection with the cooking mechanism from the top lever may, ofcourse, be made in other ways than by connection ot' link E with leverB; for instance, said link E may engage a crank on the hammer-shaft, orwith one of the hammers. The construction I have shown is, however, adesirable one.

The extension 5 of thelbarrel is slotted, so that the bolt 4 may move tothe right in said slot-without unlocking the barrel. There is also alost motion when link E slides forward over the projection bi ot' leverI3.

The stirrup may be IOO Q v y ,282.839

What I claim is,-

l. The combination, with the barrel-lug and the cooking-lever, of astirrup connecting the two, said stirrup having a comb extending throughand outside of the Stock when breech is closed, s'o that it may be swungout of engagement with the cooking-lever, as and for the purpose setforth.

2. The combination, with the barrel-lug and cocking-lever, of a stirrupextending outside the stock when the breech is closed, and adapted to bethrown out of engagement with one of the parts, as described, and aspring to restore said stirrup to engagement with the lug and lever,substantially as described.v

3. The combination, with the barrel lug, stirrup, and frame, of thecocking-lever, as B, provided with a shoulder which engages with theframe when the gun is tilted, and serves as a stop to the furthermovement of the bar rel, substantially as shown.Y

4. The combination, with the hammer-shaft, of a cooking-lever having ahook engagement with a stirrup connecting to the barrel-lug, andextending outside the stock when the breech is closed, and having alink-connection with the locking post and lever, all the parts beingconstructed and combined substantially as shown and described.

5. The combination, with the operating-lever and its post, of thelocking-bolt connected to the post, as' described, so as to move in onedirection, but to permit a lost Amotion by the post when the lever isturned in the other direction, the link and connections, and thecocking-lever, constructed as described, to permit a lost motion of thelink when the lever and post are turned in one direction, allsubstantially as stated.

6. The combination of the operating-lever and its post, the locking-boltwhich permits lost motion of the post in one direction, the link andcooking-lever and connections, constructed as described, to permit lostmotion between the link and lever, the hammers, and the stirrupconnecting the cocking-lever with the barrel-lug, all arranged andoperating in relation to each other substantially as shown and setforth.

In witness whereof I have hereunto set my hand this 16th day of May,1883.
